How to Keep Your Face the Same in AI Photos

Why AI changes your face

An image model does not cut and paste your face into a new scene the way a designer would in Photoshop. It reads your photo, then draws a new image that tries to match your request. Your face is one of many things it is trying to match, alongside the outfit, the light, the pose and the style. When your request pulls in a strong direction, the face can move too.

Google says its Nano Banana model was built with a focus on keeping a consistent likeness of people and pets across edits, which tells you this is a known hard problem that app makers are working on. Even so, small differences appear, and they grow when you edit the edited picture again and again.

• Beauty bias: many models lean towards smooth skin, slim faces and lighter tones unless told otherwise.
• Big changes at once: a new outfit, scene, light and art style in one prompt gives the model licence to redraw everything.
• Weak source photo: a blurry, side-on or heavily filtered selfie leaves the model guessing.
• Style words: "3D cartoon", "oil painting" or "anime" push features towards that style by design.
• Long chains: every follow-up builds on the last output, so tiny shifts add up.

Start with a photo that shows your real face

The model can only keep what it can see. A good source photo does more for likeness than any clever wording. Pick a recent photo where your face fills a fair part of the frame, the light is even, your eyes are open and nothing covers your forehead, eyes or mouth.

Turn off beauty mode and heavy filters before taking the photo. If your camera already smoothed your skin and slimmed your cheeks, the AI will treat that as your real face. Our photo checklist for AI editing covers lighting, angle and file quality in detail.

Wording that tells the model your face matters

Put the face instruction near the start and repeat it when you follow up. Be specific about the features that tend to drift for you. Our prompt generator adds a keep-face line automatically, but here is what it does and how to extend it.

• Basic line: "Keep my face exactly as in the uploaded photo: same facial features, skin tone, hairstyle and age."
• Stop beautifying: "Do not smooth my skin, slim my face, lighten my skin or change my makeup."
• Name your marks: "Keep my mole on the left cheek, my glasses and my beard shape."
• Keep the expression: "Keep my natural smile with teeth showing" or "keep my calm, closed-mouth expression".
• Limit the job: "Only change the background. Do not change anything about me."
• For groups: "Keep every person's face, height and skin tone as in the photo. Do not add or remove anyone."

Avoid vague praise words such as "beautiful", "flawless" or "perfect skin". They invite the model to improve your face, which is exactly the change you do not want.

A step-by-step routine for keeping likeness

1. Open a new chat and upload your best source photo.
2. Ask for the smallest useful change first, usually the background or the light.
3. Compare the result with your original side by side. Look at eye shape, nose width, jawline, eyebrows, hairline and skin tone.
4. If something drifted, name it: "My nose is narrower than in the original. Match the original nose exactly."
5. Once the face is right, ask for the next change, such as the outfit, while repeating the keep-face line.
6. After three or four rounds, if the face keeps slipping, start a new chat and upload the original photo again rather than the edited one.
7. Save the version you like before experimenting further, so you can go back.

ChatGPT's selection tool can help here. OpenAI's help page explains that you can highlight one area and describe a change there, though it warns highlights are not always precise. Selecting only the background and asking to change it can reduce face changes, but always recheck. Gemini's tips from Google describe the same idea of changing specific parts of an image while preserving the rest through a conversation.

Styles and situations where faces drift most

Pages such as 3D figurine prompts, retro Bollywood prompts and family prompts already include keep-face lines written for those styles.

Respect other people in your photos

Keeping faces accurate also matters for the other people in your picture. Edit photos of yourself, or of family and friends who have agreed. Google's Gemini privacy page asks users to get permission before using other people's faces or voices in Gemini. For children, keep their real age, do not make them look older, and think twice before posting the result publicly.
